Begin the rear door lock installation process by checking the door lock packing needs new material replacement if used before and the packing surface should always be free from dirt or grease. Put on MP grease to the moving and turning areas of the front door lock before you install the rear door inside locking cable and activate its three claws and close the cover. Place the rear door lock remote control cable to its position and engage the claw before closing the cover. The new door lock wire harness seal must be mounted onto the rear door lock and the rear door lock must be inserted into the rear door outside handle release plate while the rear door panel is set so that the rear door outside handle frame remains locked. Install the rear door lock using the "TORX" socket wrench T30 on its 3 screws which require Toyota Genuine Adhesive 1324 or Three Bond 1324 or an equivalent product applied to the screw threads and undergo torque application to 5.0 Nm (51 kgf-cm, 44 in-lbf). Connect the connector, then proceed to install the rear door window regulator sub-assembly, rear door glass sub-assembly, rear door quarter window Weather Strip, rear door window division bar sub-assembly, rear door glass run, rear door belt moulding assembly, rear door Weather Strip, rear door check assembly, rear door service hole cover, rear door trim bracket, rear door glass inner Weather Strip, rear door trim board sub-assembly, rear door inside handle bezel, and rear door armrest base upper panel. Apply the cable to the negative battery terminal then tighten it to 5.4 Nm (55 kgf-cm, 48 in-lbf).
